If your old card has expired and you'd like to register your new card in your MoPlay account, you'll need to make a deposit using your new card details. To do so, please go to 'Account', click on 'Top Up' and select 'VISA'.
Enter the amount you wish to deposit and click on 'Deposit'. At the top left corner you'll see a 'New Card' button. Click on it and introduce the new card details.
If the card has the same number as the old one but a different expiry date, then the details will be overwritten and you'll see only one card in your account.
If the card has a different number and expiry date, then the new card will be saved, however you will be able to see the old card details as well - please make sure to click on the correct card when making deposits.
